Claims.

This invention relates to package containers or the like moreparticularly for displaying articles of food such as cakes, pastries orother bakery products.

5 An important object of the invention is to provide a display containerof the class described which can be produced at a minimum cost and whichwill be sufciently sturdy to withstand the usual handling to which suchgoods are subjected while, at the same time protecting the contents bothagainst mutilation and against exposure to the air.

Other objects and advantages will be apparent from the followingdescription taken together with the accompanying drawing illustratingembodiments of my invention in which- Figure 1 is a perspective View ofone form of the invention; and

Figure 2 is a section taken on the line 2--2 of Fig. l.

Referring in detail to the embodiment shown in the drawing, the body 26may be of light ilexible material having a bottom part 21 but only twosides 28, 29, these being of greater height than that of a cake or thelike superposed on the pad Si), and the sides 28 and 29, as shown, aremaintained in right-angular relationship with the base 2l by therectangular wire frame 3l having the parallel portions 32 and 33extending along the upper edges of the sides 28 and 29, and the parallelportions 345 and 35 connecting the parallel portions 32 and 33, thusforming, for example, a square reinforcement frame extending about theupper perimeter of the box-like formation defined in part by the frame3| and in part by the trough-like body 23.

To reinforce the body 26 and also to maintain the frame in properrelationship with the body, the frame may have a pair of depending legs36 secured medially of the members 32 and 33 and extending downwardlyrst outside the sides 28 and 2 and then through slots 31 in the sides,to abut the bottom 2l. To further secure this engagement, the sides 28and 25 may each have an integral flap 38 which is folded outwardly anddownwardly over the adjacent frame portion 32 or 33 as the case may be,and over the depending leg 35, the flap having a pair of tongues 39which are slipped through the slot 3l, one on each side of the leg. Asis shown in the drawing, the tongues 3S may also serve to maintain thepad 3) from movement away from the bottom 27 by providing an abutmentfor the pad upon any substantial movement away from the base, as best1935, Serial No. 25,779

(Cl. 20S- 44) shown in Fig. 2, the pad being substantially coincidentwith the inner area of the bottom.

The structure shown in the drawing may be entirely wrapped in atransparent closure, as by a Cellophane wrapper or the like (not shown)in which case the wrapper is supported across the opening between thesides by the frame members 34 and 35 while the cake or the likesuperposed on the pad Sil is maintained out of Contact therewith butvisible through these openings. Such a wrapper may be well known in thepackaging art.

My improved container comprises a body of normally pliable material anda relatively more rigid reinforcement member having right-anguh larlyrelated portions engaged with the frame against casual separation andmaintaining the frame in trough-like form, the whole when combined witha flexible transparent closure providing a box-like formation throughwhich the article contained is visible while maintaining the cake out ofcontact with any part of the package except the pad 3l).

It will be understood that the cake (not shown) is attached to the pad3l] by either the adhesive eifect of the initially soft icing around thelower margins of the cake, or by a few spots of icing placed on thebottom of the cake to cement it to the pad.

Having described my invention, I claim:

1. A display container comprising a body of light cardboard bent to forma bottom and two sides, a rectangular wire frame having a rectangularportion dening the upper perimeter of the body and having depending legslapping the sides thereof to engage the bottom, the body having flapsfolded upon the sides over a portion of the wire frame defining saidupper perimeter and secured to the body to maintain the assembly of bodyand frame together in box-like form.

2. The structure of claim 1 wherein the sides are slotted adjacent thebottom and the legs project through said slots.

3. The structure of claim 1 wherein the sides are slotted adjacent thebottom and the legs project therethrough, and the ap has tongues whichare inserted into the slots one on each side of the leg.

4. The structure of claim 1 wherein the sides are slotted adjacent thebottom and the legs project therethrough, and the flap has tongues whichare inserted into the slots one on each side of the leg, and wherein apad is received on the bottom substantially co-extensive therewithbetween the sides and the tongues of the aps project through the slotsto abut the pad upon any substantial movement thereof away from thebottom.

5. A display container comprising a flexible closure of relatively lighttransparent material, a body of relatively heavier material, said bodybeing exed to form a bottom and tvvo sides only, said sides being eachformed of a plurality of plies, a relatively rigid reinforcementcontacting 10 each of said sides between the plies, and means includinga pair of Wires connecting the sides and reinforcements at their topsand maintaining the sides and reinforcement perpendicular to the bottom,said transparent closure forming the other two sides and top of acomposite box-like structure formed by said body and closure jointly,the said body and Wires maintaining the closure in position and theinterior of the box-like structure being visible through the closure.
